Is Time Ripe for a Currency Union in Emerging East Asia?: The Role of Monetary Stabilization

This paper assesses the prospects for monetary integration between Emerging East Asian (EEA) economies. We develop a simple analytical framework for currency unions of small open economies. The empirical analysis looks at a number of supply-side characteristics of EEA countries highlighted by the model, distinguishing between aggregate and tradable sector structural features. Moreover, we discuss the evidence on the cross-country correlation of disturbances hitting the region. Our study indicates that, at present, EEA economies exhibit a high degree of cross-country supply diversity, while there is no compelling evidence that shocks are highly correlated across the region.
